Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure
It's a rainy morning here in Wisconsin so I thought I'd write some about my Nenuphar journey. Two or three years ago I decided to build a system around high efficiency speakers in order to see what people were talking about. I ended up with the Te...

"Parts Connexion listing for the part which is actually a 1 ohm resister not a 100 ohm resistor as the listing states.  Which interestingly enough brings the damping factor to 8."I assume the two resistances (the speaker at 8ohm and the 1ohm added...

Speaking of DF, a couple of weeks ago I was cruising the intranets reading about damping factors and came across an article by a couple of guys who put together PA systems (which explains why they talk about speaker cable lengths of 50 and 100 fee...

My Backert preamp is an original Rhythm, the 1.1 (they now sell a 1.3 version). There is a used 1.1 for sale now on Audiogon for $3500. The only thing I don't care for is that the Backerts invert polarity/phase so you have to reverse the red/black...

If you want to stay with your FirstWatt amplifier, I have had excellent results with a tube preamp from Backert. All of their models have very long tube life and are very easy to tube roll (I recommend the Mullard 12au7).Robert

As for an earlier question about speaker cables, I've had good results with my Stealth Audio pair, although I admit I haven't tried anything else.Robert

So, there was a pair of SIT-1 monoblocks listed for sale this weekend on Audiogon. They went in a few hours, and I missed them. Did anybody here pick them up?Robert

On a side note, FirstWatt has a new model out."The F8 revisits their most popular J2 model but simplifies the front end for just three signal-path devices per channel. It applies current not voltage feedback and improves on the J2 specs on bandwid...

<<For those who are using SIT-3, what preamp are you using?>>My Backert preamp uses two 12au7 tubes. Tube rolling is highly recommended. This evening I replace the stock JJs with Mullards. Amazing."My father's house has many rooms..."

Preamps are sometimes under-appreciated, with more time being focused on amps and speakers. It may have been Robert Harley who wrote that the amplifier determines the character of a system while the preamplifier determines the quality.- Robert

"I found independent power supplies for each channel to be a very substantial upgrade when I did it for my first watt f4s. I think I've said this before too, but it's a really beautiful amp that doesn't get the attention it serves, btw."I remember...

"I bought my SIT-1 Mono's (Demo's) for about $500 more than what the SIT-3 goes for new."That sounds like a great deal. Didn't they sell for $11K when new?

"Looks like the amps with 2a3 tubes are 2.5 watts/channel. Is that enough to hear at sane listening level, assuming you sit 8-9ft from the speaker?"For my "sane" levels it would be, but it also depends upon the size of your room. 20-40 sq meters i...
